How this service works
One call for a Base token: symbol, name, decimals, total supply, optional holder balance, admin-control risk screen (proxy, owner, mint, pause, blacklist, fee setters) with headline and signal count, and the current block number. Pass the token contract address and optionally a holder address. Replaces 4-5 separate lookups with one payment. Read-only live on-chain data, heuristic screen, not an audit, not advice.
Output
A single JSON object containing: token symbol, name, decimals, total supply; optional holder balance if a holder address was provided; admin-control risk flags (proxy, owner, mint, pause, blacklist, fee setters) with a human-readable headline and count of risk signals; and the current block number on Base at time of call.
Example use cases
Pre-trade token risk screen
“Before I buy this Base token at 0x4200000000000000000000000000000000000006, can you check if it has any dangerous admin controls like minting authority, a pause function, or a blacklist? I want a quick risk headline too.”
Portfolio token metadata lookup
“I need the symbol, name, decimals, and total supply for the Base token at contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — just a one-call summary please.”
Holder balance with risk flags
“Check the token at 0xd9aAEc86B65D86f6A7B5B1b0c42FFA531710b6CA on Base and tell me the balance for my wallet 0x1234567890abcdef1234567890abcdef12345678, plus flag any proxy or fee-setter risks.”

Endpoint
GEThttps://heb-utils-x402.hebutils-api.workers.dev/base-token-brief?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a consolidated on-chain snapshot of a Base ERC-20 token — especially when you would otherwise make 4-5 separate RPC calls for metadata, supply, balance, and risk signals. Ideal for pre-trade due diligence, portfolio dashboards, or agent workflows that need a quick risk screen alongside token fundamentals. Not a substitute for a formal smart contract audit; use for heuristic screening only.
Side effects
- Invalid or non-ERC-20 contract address returns an error or empty metadata
- Non-Base chain address may return incorrect or no data since the endpoint is Base-specific
- Rate limiting or RPC node issues may cause transient failures
- Holder address that is not checksummed or malformed returns an error
- Token with non-standard ABI may cause partial data or missing fields
- Network congestion on Base may slow response
